norm

getNorm()
Returns the euclidian norm of the point, that is sqrt(x*x+y*y).

normalized

getNormalized()
Returns a normalized version of the point with the same angle but a norm of one.

pos

getRotated(angle)
Return the position of point rotated around the origin.

Inherited from unreachable.instance: __new__

Inherited from object: __delattr__, __getattribute__, __reduce__, __reduce_ex__, __setattr__

Static Methods

DPoint

fromPolar(angle, radius)
Converts polar to cartesian coordinates.

Method Details

hash(...)
(Hashing function)

hash(x)

Overrides: object.__hash__: (inherited documentation)

init(...)
(Constructor)

x.__init__(...) initializes x; see x.__class__.__doc__ for signature

Overrides: object.__init__: (inherited documentation)

repr(...)
(Representation operator)

repr(x)

Overrides: object.__repr__: (inherited documentation)

fromPolar(angle, radius)
Static Method

Converts polar to cartesian coordinates. angle is in radians with 0 being the positive x axis. Assuming that y points downward, angle is clockwise.

Returns: DPoint

getRotated(angle)

Return the position of point rotated around the origin.

getRotated(angle, pivot) -> pos Return the position of point rotated around pivot.

Returns: pos
